As best shown in Fig. 7, the side edges of the screen or mesh 10 ride in grooves 30 formed in sheet metal members 31 which are rigidlycsecuredgto ithe frame 4V12 by screws 32, or the-equivalent.

It will be noted that each sheet metalguide 31 comprises integral flanges 34 and 35 'proj ectin'g'inwards from the-sides Yof the `Win-dow opening, the flanges v35beingbent'to provide a bracket portion 36 through Which the screws v 32 project. e

` At each ofthe four corners ofthescreenor mesh 10, a substantially U-shaped metallic clipf38fis:providedathe clipsf3-8 being.- adapted to ride in the slots or grooves 30 (see Righi).
